Osteospermum plant named ‘Sunny Fiona’

ABSTRACT

A new and distinct cultivar of  Osteospermum  plant named ‘Sunny Fiona’, characterized by its upright and mounded plant habit; freely branching growth habit; freely flowering habit; daisy-type inflorescences with oblanceolate-shaped ray florets that are initially light pink in color becoming dark pink in color with development; and good garden performance.

Botanical designation: Osteospermum ecklonis.

Cultivar denomination: ‘Sunny Fiona’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Osteospermum plant, botanically known as Osteospermum ecklonis, and hereinafter referred to by the name ‘Sunny Fiona’.

The new Osteospermum is a product of a planned breeding program conducted by the Inventor in Odense, Denmark. The objective of the program is to create and develop new Osteospermum cultivars with compact and uniformly mounded plant habit, freely flowering habit and attractive inflorescence coloration.

The new Osteospermum originated from a cross-pollination by the Inventor in May, 2003 of a proprietary selection of Osteospermum ecklonis identified as code No. 50.003.02, not patented, as the female, or seed, parent with a proprietary selection of Osteospermum ecklonis identified as code No. 10.005.02, not patented, as the male, or pollen, parent. The new Osteospermum was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled environment in Odense, Denmark in July, 2004.

Asexual reproduction of the new Osteospermum by terminal cuttings in a controlled environment in Odense, Denmark since January, 2005, has shown that the unique features of this new Osteospermum are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar Sunny Fiona has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Sunny Fiona’. These characteristics in combination distinguish ‘Sunny Fiona’ as a new and distinct cultivar of Osteospermum:

-   -   1. Upright and mounded plant habit.     -   2. Freely branching growth habit.     -   3. Freely flowering habit.     -   4. Daisy-type inflorescences with oblanceolate-shaped ray         florets that are initially light pink in color becoming dark         pink in color with development.     -   5. Good garden performance.

In side-by-side comparisons conducted in Odense, Denmark, plants of the new Osteospermum differ from plants of the parent selections primarily in ray floret color as plants of the female parent selection have dark purple-colored ray florets and plants of the male parent selection have white-colored ray florets.

Plants of the new Osteospermum can be compared to plants of the Osteospermum cultivar Sunny Elizabeth, disclosed in U.S. Plant Pat. No. 16,564. In side-by-side comparisons conducted in Odense, Denmark, plants of the new Osteospermum differed from plants of the cultivar Sunny Elizabeth primarily in ray floret color as plants of the cultivar Sunny Elizabeth had pink-colored ray florets with purple-colored stripes.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used. The aforementioned photograph, following observations and measurements describe plants grown in De Lier, The Netherlands during the spring in a glass-covered greenhouse and under conditions and practices which approximate those generally used in commercial Osteospermum production. During the production of the plants, day temperatures ranged from 10° C. to 20° C., night temperatures averaged 10° C. and light levels ranged from 200 to 800 watts per square meter. Measurements and numerical values represent averages for typical flowering plants. Plants were pinched one time and were about 15 weeks old when the photographs and description were taken.
